Digital Front Panel for Regenerative Industrial Treadmill
Description:
A bidirectional industrial treadmill with a speed range of +/- 12 mph is currently powered by
an analog regenerative control using an external speedpot to adjust the speed. Unfortunately,
the speed pot does not offer enough accuracy and repeatability to allow for proper operation
of the treadmill. A DP4 has been added to the system to give it a quick and easy to use digital
front panel. The DP4 has also been wired to support an external jog switch for rapidly (and
temporarily) setting the belt speed to a predetermined value of 5 mph. An enable switch allows
the user to immediately force the regen to a stopped conditional should it be necessary. For
safety reasons, the unit will default to zero output when power is initially applied.
